A statistical analysis of French teachers’ blogs: beyond institutional perspectives : Some changes in the teaching profession made visible by the study of their blogs

Authors : Muriel Epstein, Nicolas Bourgeois

Our search for new sources of analysis has led us to build a quantitative inductive method based on the analysis of lexical fields (topic models) to study teachers’ blogs.

This approach generates new insights about teachers’ concerns in expected areas, such as their discipline or their own use of digital technology, but also in unexpected areas, such as dress code issues, or terrorist attacks.

This article presents our method, and explains how and why it provides us with new opportunities for the analysis of a relatively new type of written source, namely blogs.

Dynamics of co-authorship and productivity across different fields of scientific research

Authors : Austin J. Parish, Kevin W. Boyack, John P. A. Ioannidis

We aimed to assess which factors correlate with collaborative behavior and whether such behavior associates with scientific impact (citations and becoming a principal investigator). We used the R index which is defined for each author as log(Np)/log(I1), where I1 is the number of co-authors who appear in at least I1 papers written by that author and Np are his/her total papers.

Higher R means lower collaborative behavior, i.e. not working much with others, or not collaborating repeatedly with the same co-authors. Across 249,054 researchers who had published ≥30 papers in 2000–2015 but had not published anything before 2000, R varied across scientific fields. Lower values of R (more collaboration) were seen in physics, medicine, infectious disease and brain sciences and higher values of R were seen for social science, computer science and engineering.

Among the 9,314 most productive researchers already reaching Np ≥ 30 and I1 ≥ 4 by the end of 2006, R mostly remained stable for most fields from 2006 to 2015 with small increases seen in physics, chemistry, and medicine.

Both US-based authorship and male gender were associated with higher values of R (lower collaboration), although the effect was small. Lower values of R (more collaboration) were associated with higher citation impact (h-index), and the effect was stronger in certain fields (physics, medicine, engineering, health sciences) than in others (brain sciences, computer science, infectious disease, chemistry).

Finally, for a subset of 400 U.S. researchers in medicine, infectious disease and brain sciences, higher R (lower collaboration) was associated with a higher chance of being a principal investigator by 2016. Our analysis maps the patterns and evolution of collaborative behavior across scientific disciplines.

‘Publication favela’ or bibliodiversity? Open access publishing viewed from a European perspective

Author : Pierre Mounier

A number of initiatives exist in European countries to support open scholarly communication in humanities and social sciences.

This article looks at the work of Open Access in the European Research Area through Scholarly Communication (OPERAS), a consortium of 36 partners from all over Europe, including many university presses, that is working to build a future European infrastructure to address the challenges in open access publishing.

Their initial study, OPERAS‐D, revealed a variety of models among the partners influenced by national cultures. Although the partners’ activities were found to be fragmented, they also reflect the ‘bibliodiversity’ that exists in European societies.

To address the challenge of fragmentation, it is argued that, by following a cooperative model, European actors can benefit by sharing expertise, resources, and costs of development for the good of all.

As a future infrastructure to support open scholarly communication across Europe, OPERAS aims to coordinate a range of publishers and service providers to offer researchers and societies a fully functional web of services to cover the entire research lifecycle.

The Scientific Prize Network Predicts Who Pushes the Boundaries of Science

Authors : Yifang Ma, Brian Uzzi

Scientific prizes are among the greatest recognition a scientist receives from their peers and arguably shape the direction of a field by conferring credibility to persons, ideas, and disciplines, providing financial rewards, and promoting rituals that reinforce scientific communities.

The proliferation of prizes and links among prizes suggest that the prize network embodies information about scientists and ideas poised to grow in acclaim. Using comprehensive new data on prizes and prizewinners worldwide and across disciplines, we examine the growth dynamics and interlocking relationships found in the worldwide scientific prize network.

We focus on understanding how the knowledge linkages among prizes and scientists’ propensities for prizewinning are related to knowledge pathways across disciplines and stratification within disciplines.

We find several key links between prizes and scientific advances.

First, despite a proliferation of diverse prizes over time and across the globe, prizes are more concentrated within a relatively small group of scientific elites, and ties within the elites are more clustered, suggesting that a relatively constrained number of ideas and scholars lead science.

Second, we find that certain prizes are strongly interlocked within and between disciplines by scientists who win multiple prizes, revealing the key pathways by which knowledge systematically gains credit and spreads through the network.

Third, we find that genealogical and co authorship networks strongly predict who wins one or more prizes and explains the high level of interconnections among acclaimed scientists and their path breaking ideas.

Identifiers for Digital Objects: the Case of Software Source Code Preservation

Authors : Roberto Di Cosmo, Morane Gruenpeter, Stefano Zacchiroli

In the very broad scope addressed by digital preservation initiatives, a special place belongs to the scientific and technical artifacts that we need to properly archive to enable scientific reproducibility.

For these artifacts we need identifiers that are not only unique and persistent, but also support integrity in an intrinsic way. They must provide strong guarantees that the object denoted by a given identifier will always be the same, without relying on third parties and external administrative processes.

In this article, we report on our quest for this identifiers for digital objects (IDOs), whose properties are different from, and complementary to, those of the various digital identifiers of objects (DIOs) that are in widespread use today.

We argue that both kinds of identifiers are needed and present the framework for intrinsic persistent identifiers that we have adopted in Software Heritage for preserving billions of software artifacts.

Open Access Policy in the UK: From Neoliberalism to the Commons

Author : Stuart Andrew Lawson

This thesis makes a contribution to the knowledge of open access through a historically  and theoretically informed account of contemporary open access policy in the UK (2010–15).

It critiques existing policy by revealing the influence of neoliberal ideology on its creation, and proposes a commons-based approach as an alternative. The historical context in Chapters 2 and 3 shows that access to knowledge has undergone numerous changes over the centuries and the current push to increase access to research, and political  controversies around this idea, are part of a long tradition.

The exploration of the origins and meanings of ‘openness’ in Chapter 4 enriches the understanding of open access as a concept and makes possible a more nuanced critique of specific instantiations of open access in later chapters.

The theoretical heart of the thesis is Chapter 5, in which neoliberalism is analysed with a particular focus on neoliberal conceptions of liberty and openness. The subsequent examination of neoliberal higher education in Chapter 6 is therefore informed by a thorough grounding in the ideology that underlies policymaking in the neoliberal era.

This understanding then acts as invaluable context for the analysis of the UK’s open access policy in Chapter 7. By highlighting the neoliberal aspects of open access policy, the political tensions within open access advocacy are shown to have real effects on the way that open access is unfolding.

Finally, Chapter 8 proposes the commons as a useful theoretical model for conceptualising a future scholarly publishing ecosystem that is free from neoliberal ideology. An argument is made that a commons-based open access policy is possible, though must be carefully constructed with close attention paid to the power relations that exist between different scholarly communities.

Liberation through Cooperation: How Library Publishing Can Save Scholarly Journals from Neoliberalism

Author : Dave S. Ghamandi

This commentary examines political and economic aspects of open access (OA) and scholarly journal publishing. Through a discourse of critique, neoliberalism is analyzed as an ideology causing many problems in the scholarly journal publishing industry, including the serials crisis.

Two major efforts in the open access movement that promote an increase in OA funded by article-processing charges (APC)—the Open Access 2020 (OA2020) and Pay It Forward (PIF) initiatives—are critiqued as neoliberal frameworks that would perpetuate existing systems of domination and exploitation.

In a discourse of possibility, ways of building a post-neoliberal system of journal publishing using new tactics and strategies, merging theory and praxis, and grounding in solidarity and cooperation are presented.

This includes organizing journal publishing democratically using cooperatives, which could decommodify knowledge and provide greater open access.

The article concludes with a vision for a New Fair Deal, which would revolutionize the system of scholarly journal publishing by transitioning journals to library publishing cooperatives.
